BRIDOL is the British Sundial Society's Register of Fixed and Mass Dials, which gives detail and photographs of about 8000 fixed sundials and 3000 mass dials in the UK.
Some of these are in private gardens, but the majority are publicly available.
Roman numerals 5am to noon, with half hours, but drainpipe and wiring make it hard to see. Decorative border between numerals and hour lines. Engraved directly into the masonry of the wall. It is unusually low, the lower edge being only 1530 from ground level. The gnomon root would have been in the mortar line at the top.
